Which of the following solutions has the highest concentration of hydroxide ions [OH^-]? A)pH = 3.21 B)pH = 7.83 C)pH = 10.93 D)pH = 12.04

Question

Quizplus · Accepted Answer

The pH scale is inversely related to the concentration of hydrogen ions (H+) in a solution, meaning a higher pH value indicates a lower concentration of H+ ions and a higher concentration of hydroxide ions (OH-). A solution with a pH of 12.04 is more basic (alkaline) than the others listed, indicating it has the highest concentration of hydroxide ions.
